Answer 2

[Nhók Bạch Dương]

a)\(\frac{4^2.4^3}{2^{10}}=\frac{4^5}{\left(2^2\right)^5}=\frac{4^5}{4^5}=1\)

b)\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2.5\right)^5}{\left(0,2\right)^6}=\frac{\left(0,2\right)^5.3^5}{\left(0,2\right)^5.0,2}=\frac{3^5}{0,2}=1215\)

c)\(\frac{2^7.9^3}{6^5.8^2}=\frac{2^7.\left(3^2\right)^3}{\left(2.3\right)^5.\left(2^3\right)^2}\)

d) \(\frac{6^3+3.6^2+3^2}{-13}=\frac{2^3.3^3+3^2.2^2+3^3}{-13}=\frac{3^3.\left(2^3.2^2+1\right)}{-13}=-3^3=-27\)
